VALVE-STOPPER AND MEASURING DEVICE.

SPECIFICATION forming part of Letters Patent 'N o. 557,931, dated April '7, 1896. Application filed September 16, 1895. $erial No- 562,'705- (Nomodeh) To aZZ whom it may concern:

Be it known that I, CORNELIUS EMERIOK WVYCKOFF, of Brooklyn,in the county of Kin gs and State of New York, have invented new and Improved Valve-Stoppers and Measuring Devices for Original Packages, of which the following is a full, clear, and exact description.

This invention relates to valve-stoppers and measuring devices in connection therewith for packages for containing liquids, medicinal preparations, or toilet powders; and the object of the invention is to provide a valvestopper adapted to prevent the refilling of a package after the same shall have been emptied of its originalcontents, and, further, to discharge the contents of the package in measured quantities.

I will describe a device embodying my invention, and then point out the novel features in the appended claims.

Reference is "to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a top view of a package embodying my invention. Fig. 2 is a sectional elevation of the same, showing the package in an upright position. Fig. 3 shows a package as inverted to discharge material into the measuring device preparatory to its final discharge. Fig. 4 shows the position of the parts as the measured material is finally discharged. Fig. 5 shows a modification of the valve mechanism so constructed that there may be a continuous discharge of material from the package when the same is inverted as shown in Fig. 3, and Fig. 6 shows another modification of a portion of the valve.

Referring to the drawings, A designates the neck or outlet of an original package, and A is a cap-piece secured thereon in any desired manner-such, for instance, as by cementing it after the package shall have been filled. This cap-piece A has a contracted outlet a in its upper central portion. The interior wall of the cap-piece is substantially hemispherical, and the outer wall may be of substantially the same contour; but of course it may be of any other design without departing from the spirit of my invention.

The upper end of the neck portion A of the package is provided with an annular groove or recess a, forming a seat for the downwardly-extended annular flange a of a platevalve A designed to close the outlet of the package. This plate-valve A is shown as concaved in its upper side.

Within the cap-piece A is a spherical body A consisting of any suitable material. This spherical body A serves both as a valve-stop per for the contracted outlet a and also as a looking or retaining device for the plate-valve A -that is, when the package is inverted, as shown in Fig. 3, the spherical body will engage in a valve-seat a at the inner end of the contracted outlet a, allowing the plate-valve to fall sufficiently away from its seat to form a passage for the discharge of material from the package to the interior of the cap A, whichforms a measuring device, as well as the valve-casing, and as the spherical body A is in contact with the seat a the material cannot discharge through the contracted outlet or until the package is tilted substantially to the position shown in Fig. 4, and then the spherical body will roll to the lower side and force the plate-valve A to its seat, thus preventing a further discharge of material from the body tothe interior of the cap-piece; but the material already discharged into the cappiece may be poured out of the outlet at.

It will be seen that the spherical body A is of sufficient size to engage a portion of the upper interior wall of the cap-piece, and also engages the raised annular top portion a of the plate-valveA It may be desired to provide for a continuous flow of liquid or other material from the original package through the contracted outlet a when the package is inverted. To provide for this, I employ a spherical body A having a series of unconnected interstices 0, formed in its surface. These interstices, as

shown in Fig. 5, are of irregular or longitudinally-curved formation. In Fig. 6, however, they are shown as substantially hemi spherical depressions a. It is obvious in this construction that when a package is inverted, as shown in Fig. 5, the spherical body A will engage with the valve-seat a allowing the plate-valve A to fall away from its seat, and the contents of the package may then discharge through the interstices of the spherical body and through the contracted outlet at.

I prefer the unconnected interstices, as the same do not materially alter the spherical contour of the body A, as would be the case were continuous channels or depressions formed therein, and continuous channels or depressions would allow the insertion of a Wire or similar instrument to engage with the plate-valve.

In the construction shown and described it will be seen that it is impracticable to insert an instrument beneath the plate-valve A for the purpose of holding the same away from its seat and allow the refilling of the package by means of a pressure-pump or similar means.

The example of my improvement as first describedis adapted more essentially forpowders, medicinal compounds, or liquids which it is desired to measure in certain quantities, and the example of my improvement shown in Fig. 5 is designed, essentially, for packages from which it is desired to discharge a liquid or other material directly from the package to a receiver.

It is obvious that slight changes may be made in the construction of this device without departing from the spirit of my inventionthat is, for instance, the annular groove or channel a may be omitted and the end of the package-outlet made fiat and the lower side of the plate-valve adapted to engage thereon. It .is also apparent that the cappiece A may be made of any desired size or extended laterally, as it is only necessary in the operation of the device that the space between the top inner wall and the highest top surface of the plate-valve shall be equal to the diameter of the spherical body A or A Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A package or receptacle, having an annular channel in the upper end of its outlet, forming a valve-seat, a plate-valve having an annular flange adapted to engage in said annular valve-seat, a cap-piece secured to the outlet of the package and having a contracted outlet in its upper central portion, and a spherical body in said casing having a diameter substantially equal to the distance between the upper inner surface of the cappiece and the highest top portion of the valve, whereby when said package is inclined, the spherical body may roll laterally and serve as a lock for the valve, substantially as described.

2. The combination with the neck or outlet of a package, of a cap-piece secured thereon and having a contracted outlet, a platevalve within the cap-piece and adapted to engage the upper end of the package-outlet, and a spherical body in said cap-piece having interstices in its surface, substantially as specified.
